    Effect of the frequency of transcutaneous electrical nerve stimulation on analgesia during extracorporeal shock wave lithotripsy
    (Springer, 2004) Kararmaz, A; Kaya, S; Karaman, H; Turhanoglu, S
    In this prospective, randomised, sham controlled study, we set out to determine which transcutaneous electrical nerve stimulation (TENS) therapy modality (conventional vs acupuncture-like) is more effective as a supplementary analgesic regimen during extracorporeal shock wave lithotripsy (ESWL). Patients were prospectively randomised to one of three groups. In Group I (n=22), conventional TENS (impulse pattern: continuous at 80 Hz; intensity: 10-30 mA) was applied. In Group II (n=22) acupuncture-like TENS (impulse pattern: burst at 2 Hz; intensity: 15-50 mA) was applied. In Group III (n=22) (control group), stimulation was started at 1 mA and the intensity increased to no more than 10 mA until it produced a tickling sensation. Alfentanil was administered through a patient controlled analgesic device. Alfentanil consumption, hemodynamics and respiratory parameters, a 10-cm visual analogue pain scale, patient satisfaction, recovery and discharge times were evaluated. The consumption of alfentanil was significantly lower in Group I than in Groups II and III (P<0.0001). Pain scores were lower in Group I than in the other two groups (P<0.05). Patients in Group I were more satisfied with their analgesic medication than those in the other two groups (P<0.05). Both the time to an Aldrete score >8 and a modified post-anaesthetic discharge score >8 were significantly shorter in Group I (2.3+/-1.8, 49.1+/-14.6) than those of Groups II (4.6+/-2.2, 60.2+/-18.1) and III (4.9+/-2.8, 58.4+/-16.5) (P<0.0001 and P<0.05, respectively). We conclude that the use of conventional TENS is effective in decreasing the analgesic requirements and the incidence of alfentanil-related side effects during ESWL.

    Intraoperative intravenous ketamine in combination with epidural analgesia: Postoperative analgesia after renal surgery
    (Lippincott Williams & Wilkins, 2003) Kararmaz, A; Kaya, S; Karaman, H; Turhanoglu, S; Ozyilmaz, MA
    We designed this double-blinded, randomized, controlled study to evaluate the effect of small-dose ketamine IV in combination with epidural morphine and bupivacaine on postoperative pain after renal surgery. An epidural catheter was inserted, and the administration of morphine and bupivacaine was started before surgery. Forty patients were assigned to one of two groups (ketamine or control). The ketamine group was administered a ketamine bolus and infusion during surgery. The median visual analog pain scale (VAS) scores at rest were significantly lower in the ketamine group during the first 6 h (P < 0.01). VAS pain scores on coughing were also significantly lower in the ketantine group (P < 0.01). Cumulative postoperative total analgesic consumption was less in the ketamine group on Days 1 and 2 (P < 0.001). The first analgesic demand time was shorter in the control group (9.2 +/- 11.5 min) than in the ketamine group (22.3 +/- 17.1 min) (P < .0001). The incidence of nausea and pruritus was more frequent in the control group (P < 0.05). In conclusion, postoperative analgesia was more effective when spinal cord and brain sensitization were blocked by a combination of epidural morphine/ bupivacaine and IV ketamine.
